I'm new to Photoshop, and I was wondering if anyone could tell me how I'm doing and give me any advice. Thanks!

Awwww the second one's soo cute :D
But the first one is a bit.. squarular? I don't know how to put it, I'm not great at critiques, but the squareness at the end of the lines makes them not flow well to me, I'm sorry D: I so hate being negative...

Thanks! And please don't worry about being "negative", stuff like what you said is exactly what I was looking for.

I like the top one, as well as the second. The top is more of a personal style, thing, I guess. Some will like it, some won't. And I'm with Arumaixana 100% on the cuteness factor of the second. D'aw!!!
