For me, as of now ( I didn't take into consideration of any potential neighbour voting):
Semi-Final 1
Jury Vote Winner: Slovenia
Televote Winner: Cyprus
Semi 1 is really hard to predict especially for jury vote winner. Because this final is so diverse that I got a feeling the jury votes will get split between many entries. I chose Slovenia because I think it's a pretty credible and unique song, I got a feeling the juries may reward it. It may not get the top votes, but will get enough consistent votes and become the winner of the juries due to the split of the jury votes.
As for televote winner, I think it will be Cyprus given it is the only song out there with the mainstream appeal (besides Belgium, Estonia, Darude and Czech Republic, which are not really fan favourites).
Semi-Final 2
Jury Vote Winner: The Netherlands
Televote Winner: Russia
As for Semi 2, I think it's pretty clear cut. The jury vote will be a close fight between The Netherlands and Sweden, with The Netherlands edging it due to how authentic the song is.
Russia will win the televote given Sergey is a widely known European star and I am pretty sure the staging will wow the viewers. But there is a nagging feeling that The Netherlands may win the televote also if he manages to connect with the audience with this song.
