Okey. I see it now. I like it a lot

. On the side note,I really like to be able to model something like this. Well practice...
I think your done a very awesome job with the modeling part. Time to improve the textures.
Well the pictures I seen show him to have blue skin on his body. Well what is the right color anyway? Is your reference of trap-jaw have green skin?
I know it is not finished but seeing you are going to make a lot of dents on his metal part, which indicates wear, I think you also have to add rust and scratches to continue the worn look. The super new and shiny metal does not look right when it seems to have received a lot of dents. The skin too. To me it looks more like plastic used to make toys or models.
I'm looking forward for improvements you are going to make. I will keep visiting.
