I know you have a Nikon, but you might want to consider the macro clip on I just bought. About $75 US dollars--just an idea! Great job with this one, though! I have no idea what a real macro lens even looks like! :)
@darylo - It looks like a great macro clip - your photos are amazing! Looked like it works the same way as the macro filters I got, but might have to consider it ;) Thank you for the tip :D Though if I get the money I need, maybe a maco lense is what I'll get :P
