Your lines look pretty good, but if you want to take some advise from an old pinhead then this is it. Were your stripes intersect on 90 degree angles go back in and make sure the line with has the same consistency right up to the point they touch.You may have to play with it a little in the beginning but you'll get. Also keep the points pointy, run them out a little longer if you have to. Other then that your on your way. I don't know how long you've been at it but to tell you the truth Ive seen so called "PRO'S" who are charging for their work that aren't as good as you. Keep it up, your on your way!!!.
Thanks Merlin. BigNick, thanks for the feedback. This is the type of critisism I'm lookin' for. No, I havn't been striping long, 6 mos. or so off & on. Just got a look at your site and dig your lettering, I want to start doing that as well. Got any suggestions on brushes? Sizes, brands etc. Unkl Ian on this board has given me some great feedback on the subject (thanks Unk!) but I'd like the hear what you think.
