there's a safe and very satisfactory blend of points and curves in your line-work, the posture in the lines look VERY composed and original and that seems to be your focus or you bread and butter~ while the color proposes a bit more strength to your fun characters such as this one, there's so much tone and volume to the cool gestural movement in the line work. I know as a line artist that it's harder than it looks to provide such lines. I feel that there's a lot of planning and construction in the process am I wrong? With that said you present a very distinct voice in this character and coming down to appearances, there's more than just lines to it. looking at the owl, the way you've presented the shapes for an instance, the large flatly shaped pear of a head, the fat sagging cheeks. it's a real joy for me to look at. His posture and personality shows intimidation in his smart intellectual brain, or looking good for the miss, whatever it is your ideas, use of shapes and line all come in as a key factor being just as important to convey the personality and type of intellect in your characters and you do that so well. Above all I find this owl seemingly more charming than anything, I'm just putting it out there, this Owl is Brilliant! (and they're my favorite birds)
Only thing I care to add as a technical detail is that adding the owls shadow reflection on the ground to show a sense of space or something to help the composure of the piece reach it's full potential upon presentation would help, though I noticed you have done that in earlier work but please by all means treat it as a side note to really keep in mind. nothing big :]
you sir show a great amount of originality in your work. I have much admiration for original artists such as yourself. keep groovin' yeh?
