Definitely not an expert here, but overall it seems to look pretty good! One thing I do notice is that you have some equator-ward flowing currents along the southern coast of the central continent that you have as warm but seem like they should be either cool or neutral since they're coming from cooler seas and going to warmer ones. There's a similar but opposite case of some pole-ward flowing currents in the southern hemisphere that are drawn as cool but seem like they should be warm since they're flowing to cooler waters relative to their origins.
