Nice one Unsp. Some things you should know abou this.
- Improve your focal quality by using some options like blending.
- Try to use some effects up to the render and around of it but not too much.
- The resize its not right. You need to make it a little bigger.
- Also, a p.x stroke would be lovely.
- Last, use your creativity to make a lot of colors in your image not one monotone purple.
In my opinion, I like your backround but it has low quality. You need to use some sharpening many many things. I will explain it all. Anyways, keep up but you need a lot of work.
