Regardless of the intended character... The form is good, basic, but good. In the future, I'd suggest adding 더 많이 depth. 더 많이 texture overall, shading, specific detail, and highlighting -- specifically in the hair. Make it as realistic as possible, and most of all: KEEP AT IT!
My drawings used to look a lot like this, and trust me, 당신 will improve if 당신 keep going!
당신 can do this too, that's all I'm saying. Because I know how discouraged artists can feel.
The 사무용 겉옷, 전반적인 image is pretty good, but in my opinion the bubble sizes could be 더 많이 varied and the blue overlay could be a bit 더 많이 dimensional, too (I like the effect it gives, but like, perhaps in a few 더 많이 different shades of blue, does that make any sense??)
