Hi Silvia! Glad to see you around 
There isn’t such thing as a silly question!
I think this cover became pretty punky and so it may have some flavour of all the styles related to it.
I hadn’t thought of ska (which I really like), but the amount of distortion I use isn’t usually the setup you would choose for that style.
Also, rhythm is very loose in ska and and this song is pretty straight forward.
Maybe the previous cover I posted might sound a bit more ska -ish due to the strumming pattern I used, with off beat uptrums all over the place:
Thanks for having a look and, of course, enjoy your Xmas and have an excellent new year.
Cheers!
