few points...
OK it seems that there are some kids here posting pics of not so good handstyles...I think it's all ok as long as you know you suck. Someone already asked about this and wasn't being an ass about it so I might just well give you a few tips. these are my points ONLY. I'm not saying, I'm just telling. Some things i've figured out myself and some were told to me in 1995 you can disagree all you want but if you do, just post your own comments and make it count.
how to develop your handstyle? well get 200 sheets of normal deskjet paper and a pencil. the more paper the better. then start bombing. bomb the sheets both sides, every white spot that can fit a tag you must fill with one. while at it, try to figure out what looks good. I'm not telling you to copy letters from others and bite handstyles. I'm saying you need to find out what's your favourite element in tags, what makes a tag look good in your eyes? is it curvy, edgy quick, calligraphic or what. do you want a fast one without taking the nib off the wall handwriting style or something else? I guess everyone at some point took heavy influence from another tag... it just doesnt have to be straight up biting the most obvious legend every kid knows in your neighbourhood. just fucking think about what kind of tag you want to have and practice it on paper until you're satisfied and you control it every time. it'll take time to get it correctly on the walls, it's different to make with a can and a marker...and most likely next year you'll think you sucked, but it's all part of the development in my book. my style still changes constantly and I don't consider myself a veteran at all.
