it seems like something done in flash, no offense. maybe next time, this could help: try not to make ends of vector lines get skinny unless you are using a pen and are airbrushing something with a tablet, also, keep in mind that most vectors are put close together for detail reasons, if i am wrong, please do correct me. i find it is much more necessary as an artist to add a lot more features and detail to a vector to keep it at its finest, but don't over-do it; a vector must keep 2 things in it at all times: detail, and most importantly, simplicity. by using those 2 things in your next vector, i am very VERY sure you're next one will look astonishing! great job on it so far, though! looking forward to the next one! and please correct me if i said anything that has nothing to do with vectoring, as i am somewhat not so intelligent at the complex art form.
