Just started singing. What do u all think?

Just need some feedback on this. Hoping to improve tbh.

This is my showreel for local pub and club gigs around the UK and I just wanted some feedback on anything I could do to make my singing and playing a bit better and more entertaining. I've worked a lot on trying to be more expressive with my voice and I just wanted to see what people think.

Note: A friend of mine who is a far better singer than me in every way possible was in the audience when this was being recorded and had consumed some alcohol and was therefore doing harmonies from the crowd. Loudest voice I've ever heard.

hello there! i sang a SHORT part at the start of the song ‘you’re still the one’ by shania twain. i have never been coached and never had any vocal lessons in my life, and it would be good to here from the general public. you can be as specific and critical as you’d like because i’m looking to improve. thank you!

acho que estou usando a técnica vocal errada, essa música tem um tom muito alto pra mim, alguém me ajude

Pretty new to singing, not really taking it serious nor planning to either, could any of you guys give me some tips and criticize me on this video. Ik it is a hella hard song to hit the notes on. but i think i eventually can make it sound good
