Guitars aren't bad... for a start! They need more depth and space though...
Oh my... the vocals... lots of work needed here. For one, performance, performance, performance.... they are consistently flat in many places. Backing vocals and doubled parts usually have to be bang-on in terms of the timing of the phrasing, otherwise it just sounds sloppy.
The mic you used sounds like a low-grade dynamic.... it sounds muddy and indistinct. Careful use of EQ might help, but one future upgrade should be some flavour of condenser mic combined with a mic pre. Tex mentioned the SM57 -- although not a condenser, you will notice a definite big improvement over your current mic.
When you record, you constantly have to be thinking and planning for the space around your tracks, and how they will fit in the "stage" between your speakers. Use of EQ controls the stage positions on the vertical plane (lows to highs), PANNING controls the stage position on the horizontal plane, and DELAYS/REVERBS control the depth or front-to-back plane.
Keep at it -- the more you practice and familiarize yourself with it, the easier it becomes.
