How can I make it better?:)

By putting a penis on it and selling it for 500$ to furries.

A fat gold chain, cool sun glasses, swaggy hat, joint and a ghetto blaster :) If you really gonna draw this, @ me in the comments:D

Give her a tatas

A little less edge on that middle finger

By not letting him show us the finger. Otherwise, very nice fucking drawing.

I'd say the colors you have chosen are nice, but the coloring technique could be better. Plus you need to add light / shadows to give it more depth, it feels a bit flat atm. But pretty nice overall, keep training and you may draw it again in one year with even better results!

Now draw furry porn and get rich

Tattoo it on a mates arse freehand

Put a blonde lady on top of it
