Wow, great cover, I love the vintage texture and the stickers are a very nice touch were they photoshopped too? Also fantastic work on the character, i love the warm colour and shading and the pose is especially well drawn. I love how she fits the boundaries of the page, very nice indeed
I love your style, and the girl looks so pretty. I love her eyes, lips and especially her boots, they look so cool. I love the colors, they are kinda simple, but it really suits the image.
If I may offer you a small critique, I'm not half the artist that you are, I know, but I can see something wrong with the anatomy. The boobs are a little flat, I mean unnaturally and oddly so. I would suggest looking at photos of women laying on their backs, and you will see what I mean. When we lay on our back is when our boobs kinda look the fullest, they sit on top of our rib cage and it makes them really pop out. With the boob as it is now, it looks a little saggy, and ages her a bit. Even if she does have big boobs, they still shouldn't sag that way. So do I, and I know when I lay on my back they don't lay like that, I dunno. I really do like it, please don't think I don't, I just noticed and thought I would offer my advice, I know you probably don't need it from a very amateur artist as me, but there it is anyhow.
Anyways, you do lovely artwork, it's always so nice to see unique art styles such as yours.
