Please comment on my pronunciation

I'm trying to master American pronunciation. Could native American speakers please listen to the following recording I've posted on YOUTUBE and let me know which sounds I need to improve. Thank you!

You seem to have a problem with the "v" in however. Also, I detected a problem with abuse/abuse. (It's pronounced differently as a verb than it is as a noun.) Mostly, however, it's pretty good.

Thanks for taking the time to listen to and comment on my recording. Are there any sounds that stand out as CONSISTENTLY mispronounced?

I have posted a couple of more short recordings, one addressing rhoticity (-ar, -or, -er) and the other one addressing the full and reduced 'u' sound.

I really appreciate your help!
