Can you figure out the theory of my guitar playing?

[Andrew Fernandes]

So I jammed around came out with a chord progression. I was wondering if anyone knows if there is like a special word or something that has something to do with my playing like a specific style or if it sounds like something you’ve heard. It is refreshing to know if I am doing something special or elaborate. My arpeggiated chords were aspired by the first progression. Any words of wisdom greatly appreciated.

The progression likely is in either Em or in C. First off I would advice to just put your pinky on the 3rd fret of the D string instead of sliding up 2 frets because it makes playing it a bit easier.
If the progression is in Em the harmony would be i-VI-Vi-Vi. If it is in C it would be iii-I-Vi-I since the harmony in C doesn’t really make a lot of sense it is probably in Em(there’s no hint of closure cadences whatsoever).
For the arpeggiated part it seems like you’re doing C-D-Am-C-D where the harmony seem to be I-II-Vi-I-II. However I would prefer to look at it like VII-I-v-VII-I since it kinda hints a perfect cadence(v-I). What you know from this particular one is that if you pick C as the one chord it is in C lydian and if you pick D as the one chord it is D mixolydian.
I hope this helps!
Don’t hesitate to ask if you don’t understand something!

Thanks, Ids for your answer and watching my video!! The part I don’t understand is the roman numerals. I do a slide, I feel like that must be the inner metal in me doing that. It feels like the ding on the drum in chapter four in the intro dadadaddadaddad ding. I made it like more bassy so it would be good for a backing track for a solo I think (the arpeggios). The chords strumming sounds a little sporadic which I like I quite admire the c to d slide and then I do the c chord again and touch the 3rd fret b string to sort of remind you of that note, from the previous d chord (c shape) which also has the same 3rd fret b string note.

I think I tried to make the arpeggios a bit more complex and tried to resolve it a bit better now.
Hopefully its an improvement I also tried to use a metronome.
