I disagree, just because you're not good or comfortable at something or just because abstract is a niche (not sure I agree with this either), doesn't mean you shouldn't have at it. So you failed, at least you tried!
#1 Personally, I can't see any frost. It just looks like white shingles to me.
#2 It's not level.
#3 I think you'd be better off with sharpness throughout on this shot. That will remove the depth and will further the illusion of compression that your focal length is already giving you.
#4 I agree with BlackSheep, this is basically a texture shot. The lines only lead side to side, there is no subject, no feeling, seemingly no thought given to it.
#5 It looks soft overall... what lens and settings?
Keep trying!
