The first time beat dosent sound bad at all, the bassline sounds good however as Mason mentioned yyou could have used better sounds to compliment each other. I also feel that the sound levels are really low, drums & kicks should bang & the bassline should thump. You might wanna fuck with the eq for that.
The violinical beat was good imo esp towards the middle/end with the progression of the elements of sounds you were using. Both may be missing a simple element here & there but overall not bad for your 1st joints. Just work on eq'ing to make your joints bang. In due time you will get better & master your craft & possibly even develop you own signature sound as I did when I was comminng up.
I myself don't mess with cpu software for music, I like hands on creation but possibly in the near future look to evolve in FL or some other vst's.
Ill be looking forward BB to see how you progess in your production. Add me on reverbnation. peace
