I really like the marks you make, your brushstrokes have a very nice feel to them. The quality of your work seems to be a bit inconsistent at times though, both between works and within the work itself. Sometimes a face or a torso looks greeeeaaat and then the pose is awkward, the character is unbalanced or the eyes are skewed.
Sony has a point to some degree. I do think producing a lot and not lingering on the details isn't that much of an issue since your rendering seems to be coming along fine, but do take the time to iron out the glaring mistakes out of your sketches, like skewed eyes, unbalanced poses and awkward hands. Finally getting those things right will help you learn a lot for the next time, not to mention great satisfaction!
in your first page at post 1 especially in the 4th img there seems to be some texture?Also in your last post the images have some grittiness.Perhaps you re using filters man or texture with the round brush, i dunno but standard round brush from what ive seen with the default settings doesnt produce this kind of texture and again correct me if iam wrong
