4/10,
Seems like you like to make rediculously big sigs. If you're doing that because the renders you use are too big, just resize them.
The backgrounds that you make are somewhat "repetetive", meaning it's sorta boring because:
(1. Theres little depth to any of them
(2. The brushing/filtering is predictable
Although I see some progress, I think you could take bigger strides if you read some tutorials.
