Any tips/suggestions on my painting..? PLEASE ANSWER?

Unfortunately, I don't have any suggestions for your painting. Admittedly I'm not very good with symbolism =P but I can recommend a great genre of paintings that are all about symbolism and should give you some inspiration hopefully! It's called Vanitas, a sub-category of Memento Mori (which also might interest you). Wikipedia has a good article on these two genres and there are probably lots of websites. If you do decide to go with something like this, be careful that you don't make it too clich�. These themes have been around the block a few times =P
