Thank you!Sure! But there are a few pieces of advice I'd give!1) For client work make sure you scan your work, and your scans are clean on the page.2)Don't watermark your work (particularly the deviantart watermark), it's distracting from the art, and simply signing it is enough.3) When drawing characters try to use composition and efficient use of your page. Some of your characters are placing in slightly distracting/nonsensical ways, play around with how you place characters to make it more appealing.4) Sketch lightly, try not to smear the pencil as it dirties the page when scanning (and consider getting a putty eraser to help you, and possibly even getting a lightbox for inking). I've been using a $20 lightbox I got off amazon for a while to help me get cleaner inks. I also often sketch in red or blue pencil, as you can easily remove it if you can your traditional lineart in and color digitally. You can also scan in your traditional lineart, clean it up (play around with brightness and contrast), and then print it out again on paper that takes marker well (just make sure your printer ink can take alcohol based markers if that's what you're using).5) Finally make sure you clean up your final scanned pieces digitally. You can fix mistakes, edit colors, and even clean up particles from your printer in a program as mundane as MS paint or photo gallery, though I'd recommend something a little more high end. You can find free programs on the internet that work super well for cleanup purposes.Also consider investing in some better paper if you'd like. Printer paper totally works for sketching/inking. When I'm just doodling outside my sketchbook I use it a lot. But you can get huge reams of cardstock for pretty cheap ( You can get a ream of 150 pages for like $5 off walmart.com) , it holds marker pretty well, and if you tape it down with masking tape you can probably even use watercolor. If you get that light box, you can sketch on cheap printer paper, and ink on the cardstock and you'll have 0 messy sketch likes in your finished piece! I'm also not sure what inks you use (it looks like maybe a sharpie?), but if you want to up your inking game, invest in some Sakura Microns. They come in various sizes and you can get them for like a $1 individually off ebay. I just recently stocked up. My other personal favorite for softer inks is ballpoint pen. I did these inks yesterday with ballpoint pen on some cardstock manga paperand scanned them into my computer (and colored them digitally). Depending on what size you draw at, you can get some pretty neat results. You can get ballpoint pens in huge packs for super cheap, and they're also great for sketchbook work. The other +, most ballpoints are waterproof, so you can easily use them to ink with watercolors with great results!Here's a handy video with a list of some cheap art supplies that you can use to great effect: www.youtube.com/watch?v=gCnjJb… Hopefully this was helpful! For commissions you want a clean presentation of the finished piece, and if you have that it will make your work more marketable. Get creative and embrace the possibility of improvising and mixed media if money is scarce or you have limited resourcesBy getting some better art supplies and learning to use them more effectively, it will definitely help you grow ^ ^
