Hey Gnommy(or Thomas)
I do music production, mixing and mastering for about 10 years. I try to give you as good as feedback as possible ...
I think your sounds are good, but not great and i am talking about the choice of effects and about the execution of mixing. The sounds that you presented are very average, like the gun shot or the beam sound at 1:48. This is like the 101 of sound design
That is totally okay when you are on the look for work in that area, but i personally really like it when a sound designer creates totally individuell sounds that transport you into the game
Something that has never been done before(Yahh i know this is hard to manage
).
One thing i definitly would change is your voice. Your voice is way to small because you are using that old telephone effect. Better go for a high quality sound of your voice here and speak loud and clear, otherwise it is to hard to understand you
Best of success!
