Thoughts?

It's ok work mate but needs improvement Render work and blending are not good try to correct that Texture work could be much better, I think you only added lens flare and few textures with white dots, try to experiment more mate Not sure about the BG it's to simple imo, try to add more textures, lights and colors. Text is ok but with little more work it will look even better. KIU mate

Fine work mate
Render work looks ok. But too desaturated. Get rid of the desaturated overlay and blend it better
The bg could be better also add a texture or two. And maybe get rid of the flags and add a stadium.
Text could be improved. The clipping mask looks ok. But you need to choose a different font or something. And get rid of the multiple texts. Texture work could be better as well. Lens flare doesn't really work is these sigs mate Get some textures from the texture section, and experiment. kiu and keep practising!
