@dustymabe I added more of a foggy look here:
Was this more what you had in mind? Let me know!
I took @bhibb’s suggestion and changed that browny colour in the corner too! I am using blender for the model and then doing some post edits in GIMP! I’m still as bit new to blender so some of the things im not used to but I might try and matt-ify (?) and add some texture in GIMP and see what I come up with! Thanks so much for the feedback - it’s great getting input from someone familiar with the software
