Check my physical geography (Syelleyaa and beyond)

[Mapsburgh]

I've got a worldbuilding project centered on the small continent of Syelleyaa, which I'm trying to expand to encompass the whole planet. I've drawn up some maps in super sketchy form to hammer out the basic physical geography principles in broad strokes. Here's the basic world (brown lines are significant mountain ranges, circles show the location of island arcs):

Here's the plate tectonics:

Here's the ocean currents:

Here's the climate zones:

(Dark green = tropical forest, orange = savanna, yellow = desert, purple = Mediterranean, brown = steppe, light green = temperate)

Have at it! What am I doing right/wrong?

Nice maps! I'm not an expert on tectonics, but there's nothing in the currents which seems too far off to me, at least for a rough schematic.

Something which jumps out from the biome map is that you have a large temperate area north of the polar front at 60N. This isn't completely impossible - the polar front can wobble a bit, and the definition of "temperate" can be stretched, but I would expect the northern coast of Celsen to be a classic taiga (Köppen Dfc) - similar to northern Siberia or Canada. Lots of dark thick conifer forests and swampy ground, long cold snowy winters and short hot summers.
