I never realised that you did GFX and these two are both really good.
The Lady Gaga one is my favourite. I like the colour scheme that you chose for it and the lighting effects around the main picture are excellent. I also like how you decided to only keep the main picture fully coloured as it made it stand out even more. 8/10
The Darth Vader sig is a bit more simplistic but I really like the main picture and the lighting used on it. I am not too keen on the two background pictures as they are a bit too cartoony. 6/10
