Thanks, I would add a couple more touches or objects into this scene if only it wasn't so terribly optimized…

I made the hat using the remeshing modifier on a cone and I'm not quite sure what light artefacts you're mentioning because I just put an image texture onto the hat and started dotting on it haha, the rest is all default Principle BSDF.

The second image looks like that because I didn't have time to render the second angle with the new changes I made.

Originally, I wanted to make a street like the last image but I just couldn't really replicate the look of it without lagging my computer. I have a serious creative block after that so I just picked random objects and play around with different composition techniques rather than making more detailed models. The project started to slow down my computer and I had to limit myself on what I could add, ending up with this. The heavy fog was not intended but it took so long to render so I had no other option than to use it, playing more into the composition would have made my render take 2 days+.

 I know its not the best work I have done and I could have done better if I had consulted Jerome but I had increased work on my end and I always return late, I apologize for this. 

Thanks Jerome! I just applied a crystal-texture shader onto the cylinder and added an Emission node and really cranked that thing up so it shows well in the shots, coupled with the crystal texture.

Here's the material node map:

Hi Tomas, I got the transparent look by setting the bubble surface material to principle and dropping the alpha value down to around 0.1, the key to getting the transparency look in the screenshot was by changing the render engine from EEVEE to Cycles since EEVEE is incapable to true transparency, hopes that help!
