Yea I agree with "Pantera"....this is really going to be beautiful, and I know that with my mouse....I would never be able to get such clean lines as these are. Ohhhh... I wish I had a tablet...."LOL"!! I really am anxious to see this picture get finished!! Great job so far! :)

I concur, straight clean lines like this can be done with mouse. There is this nifty tool called "Bezier"and it lets you get smashing sleak lines.

Looks good so far

yes, it does, but it depends on how you shape those lines and tips :3 and it takes alot of patience.

Really nice so far, the lines are superb. Can't wait to see it colored :D

I think the pink in the shading on the front girl should be toned down a little, and I think it would look nice if you used a little blending and some subtle gradients. The blank space at the bottom is pretty distracting and throws off the balance a lot, so even if it's hard or time-consuming, you should try to fix that. After all, it's nice to challenge yourself sometimes.

I hope I don't sound condescending or anything --- this has a lot of potential and I'd like to see where it leads :D
