you need to be exposed in more portals. Do you have an account in Facebook? Instagram? (i know that socializing is a time consuming process but you need it)commissions will definitely go better for you in facebook.about price i cant say much, you are the one to know what your art worths (to you and to others) but if your intention is to make this a profession then i cant see how you can do this while staying in a small format (A4) and pencils. You need to try bigger and also start with brushwork.Even if this isnt your thing (or your style) you need to take the journey, this is what art is about, its like life, you need to experience every part of it.well, this is my opinion anyway, it worked for me, but i dont know you in person my friend, so i cant know your expectations either.
