hmmm....
nice dragon....!!!.... i suggest you watch out for the anatomy..(i'm not saying that you must look to a real dragon...beacuse, you know..they dont exist...xD)....find references like the monitor lizard or the komodo dragon... you can find lots of inspiration from animals...EVEN BIRDS!...take this as a suggestion...im not telling you how you should draw... its a very nice dragon just as it is....
