Lot of good thumbnails here solin. I think numbers are good. Can you just clean this up? Also, there is nothing wrong with using texture, but can you give me couple without using any texture. I'm positive that you can totally do these thumbnails without texture. In portfolio, you just have to show more process from simple thumbnails to the stage that you are doing all the way to final color rendering. Also, when you do couple shots without any texture, let's try the extreme wide angle shot and extreme close ups. Good job`!
