I think the room acoustics are interfering with your recording, it sounds right but all that free space is making it sound a bit washed out.
As for the FocusRite and a mic, take your time as it will take some getting used to and whole new learning curves in settings levels for mic recordings, etc. But, its a fun journey and a few years ago I'd say it was hard but now YouTube has literally got everything you need to get started.
