good looking comic. here are my recommendations; 1.the first page looks like its outside, that wall looks like a sky. you need a more toned down, smaller texture so it looks like a wall and not clouds. 2.the second page shots need a ceiling. without it, it gives an appearance of the scene "floating". 3.making a comic is a huge investment of time and energy. you want to make sure that when you finish you're happy with the results. I would go into a pre-production period and work out issues like lighting and cameras. do a bunch of test renders and really flesh out your lighting and cameras. if you put the in the time in a low pressure test environment your results will be much better when you're rendering for real.
