Hello there! You have been visited by a Critique Ninja! We stealthily roam the site, looking to leave thoughtful and useful criticism, as per the spirit of CRITmas . Mind if I just hop on to business, then? Just swooping in and out again - that is the Ninja way...!First things first: oh my god that little blue thing is still cute as hell. And so is his buddy! I have but a few suggestions; let's go over them:First thing I noticed was the shadows of the foilage looking 'off' in places, and I realise this is because they are individual brushstrokes at partial opacity. This has the unwanted side-effect of some parts, where the strokes overlapped, being darker, which in turn makes it look like there are two (or more) light sources, which of course is nonsense in an outdoor setting where the only light is the sun.I think you can solve this by keeping your foilage-shadow on a separate layer, filling it completely, and using a mask to decide where goes light and where goes shade. It's easy to correct / change the colour of / try things out with, and if it all goes sideways, you can simply throw away the layer and try again without hurting the picture underneath!The other thing I think needs attention is direction of light / place of shadows on your characters. It doesn't hurt to add a little 'light bulb doodle' in the corner of your canvas where you think the light should come from when you sketch in your elements, to help you keep light direction consistent. As it is, I spot a shadow on the top side of our little blue friend's arm, and one on the underside of his green pal. The light under the hand seems to suggest the light is shining down from the top, and the light on Blue's face and body suggests it comes from the right, shining nearly horizontal.Since it's still a nice picture no matter how you look at it, I'd say keep it as-is, and maybe only implement the things I mentioned in your next projects.I hope my critique wasn't too harsh. Have a nice New Year!
