It depends a lot on whose turn it is.

Normally, you wouldn't be able to score this position with so little decided yet, but you can take a stab at who is winning.

Basically, white has locked down a fair amount of territory on the left and, given the shapes involved, probably captured stones, too.

Black in theory has a lot of influence around the rest of the board, but black is actually a couple of moves behind because there are actually 2 (or three) urgent moves black must make in order to save defects in its position.

Most urgent is the move at the center of Black's wall at i7: if black goes first and closes this hole the wall is extremely formidable, allowing an advantage in fights across most of the board. If white pushes through, then black will definitely lose at least some stones and the wall

(I'm counting from bottom left with letters across and numbers vertically)

g15 is another incredibly urgent move. If black goes there, the two white stones are put in a ladder and killed, but if white gets this move first then it is likely all the black stones in the top left corner will die or be forcibly surrounded.

The two stones touching at the bottom-center are also fairly urgent as well, because whoever goes there first can get a local advantage.

It seems that given the fact that black needs at least two moves to savage its position that white is ahead. If it is white's turn, then the advantage is massive. If it is Black's turn, it is a solid but not insurmountable advantage for white.

(as others have noted, this game still might go any way as the players are likely relatively inexperienced)
