very unedgy wen vectoring making sure edges are smooth pls banner at bottom doesnt work with it trying using banner in a different way

IMO it is very good for a first logo. Its clean but the font choice isnt the best. Needs to be something bold and easy to read for whoever is viewing it.

Plus try make a background , maybe black and grey like most backgrounds. Will make it look a lot better. Then try different colour schemes

Try come up with your own ideas firstly,
Shield doesn't look right, S is two skinny, lines coming off it don't flow, lighting bolts coming off, look horrid, banner doesn't flow and needs to be different colour, Take out the watermark, looks terrible, if your selling get a better watermark so it doesn't downgrade your work like this, move banner up, but yeah just don't rip..
