First attempt in professional mixing & mastering

Hi y'all, I'm fairly new in audio engineering and mixed and mastered my first full song. I must say it was recorded very precisely, good mics, mic placement adjusted perfectly so I did not had to replace tracks or phase shift, so it was quite fun. I would love to hear your thoughts and get some critique, so I can do better next time. Plan is to offer my services soon after I have had some more experience... That would be awesome! It is part of a mixing challenge, so it would also be nice if you may give me a heart above the video, mics can be won. But I'm here for the judgment :) Mixed in the box. Vision was to have a lively (concert experience) and warm sound. Especially I'm not sure about the low end, the drum sound, the vision of the mix in general and the stereo image (depth and width). Thank you! Listen to my mix here:
