(again I’m not officially a mentor, just to let you know)
My high level comment is that there is quite a variation of difficulty of tasks which makes me wonder if you already have good ideas on how to tackle each task. For example, adding round corners to rect would be an easy one and perhaps would take less than a week, but I’m not sure implementing shadow mapping in 2 weeks is feasible considering the tests and documentations you need to cover. Given that, especially, implementing shadow mapping, multiple materials and blur filters requires really good understanding of GLSL you need to prove that you are already fluent in GLSL.
