no you are not!!.. or at least you should not!! why not?
well let me tell you: it took me ages before I made my first decent tag...
I was on an other forum back then.. my name was lexo.. I only got negative C&C, so I started arguments... ended up in fights.. in the end I was so dissapointed that I quit.., but I came back on a different name.. at first I got still bad comments, but I followed tuts and then it happened: I made this nice sig!! and got nice (even very pleasant) comments>>
and I thought yesyesyes!! (I can show you my first nice tag if you want LOL)
made me proud of myself.. and made me believe in myself again! so.... what I want to say here is: it takes time, lots of practice, lots of C&C, and lots of persistence..
so: no you should not give up; i've seen enough of you to know that there is potential (I might even say TalenT) awaiting to come out!!

edit: PS, nr 3 and 7 are prety damn good tags! I like those.
