I still struggle with textures for abstract myself. I can shoot tree bark and rocks all day, with great deatail, great shadows, great everything. But they still suck. In that they are not interesting enough for me to actually keep. I don't know how to get abstract and texture in one.
I'm not saying yours suck by the way, lol, was referencing mine. However, yours do not appeal to me as they are no different than most any of us can do within 100 yards of our house. Especially in Maine, we have rocks, jagged rock formations everywhere. lol
