This is a lot of fun and a really cool concept. I really love how you have the ravens a part of the wing - whether they're what makes up the wing or behind it, or sitting on the dragon. It's
like he's almost... curious, how he's turned towards the ravens, watching as they fly off. Maybe he'll wait for them to return. It gives a sense of peace, like they're his family, or even just his buddies off to get some food. The individual scales of the dragon and the whole birds are extremely well done - from the different wings and beaks of the birds, to the horn, tail curve and curled claws of the dragon. I also really like how the ravens still 'on' the dragon are just beaks and wings waiting to take off.
I absolutely love dragons (already have one tattoo of one and would love to get more) and this is definitely one that I would have loved to have and been proud to show off. Need you as my tattoo artist. ^^
Really amazing job!
