I definitely see where you got your influences. It is predominately traditional with a bit of a Japanese Traditional flair to it. I like how symmetrical it is without being mirrored. It's very well balanced.
It's one of the most unique view on wolves that I have seen. It seems as though they were almost combined with a Fu Dog/Lion with their flowing hair.
The blending with the existing tattoo is nice, but the hair extended so high with such a hard outline, it takes away from the fade into softness from the existing piece. I think it would have had a more cohesive feel if it had faded from hard to soft. That is really the only negative (but then again, since it's unfinished it could still easily go that way) feedback that I have for this piece.
I love your unique style and that you can easily tell who it was done by. Voice is very important to a tattoo artist since that is what draws our clients. I think it is much more refined and elegant than most other traditional artists' work.
Overall it has a very strong visual impact. It leaves you asking many questions as to it's deeper meaning since it seems to have a lot of symbolism packed into a very tough masculine piece. I look forward to seeing it finished and hope to see it with maybe just a pop of color to really make it stand out.
(I am a big fan of monochromatic tattoos with just a splash of a strong bright contrasting color to add just another dimension to pull the viewer in)
I love the design, (ok Im biased i like all your designs!) it is balanced very well on the clients back and the placement is spot on. I love how you incorporated it into the existing tattoo. I only have two things to bring to light about this design; 1. The wolves tongues are rather long to their proportion. and 2. I would love to see you use more varying line weights in your tattoos. I think the varying line weights would enhance your tattoos even further than they are now, adding a level of depth to them. Other than that I cant wait to see the finished piece!
