plot - Plotting vectors and planes in 3D with Mathematica -

-

i trying out mathematica software, , playing representing in 3d vector projections on plane.

i got point:

enter image description here

i know... not looking impressive, , ask modifying beveling of red arrowhead, changing color of plane, getting projected vector looks more shadow, , labelling vectors on plot. or of it...

here's code i've used far:

show[{plot3d[{z = 0}, {x, 0, .75}, {y, 0, .75},     axeslabel -> {x, y, z}, mesh -> none, boxed -> false,     axes -> false],   graphics3d[{red, arrowheads[0.05],      arrow[tube[{{0.25, 0.25, 0}, {0.5, 0.5, 1}}]], brown,      arrowheads[0.05], arrow[tube[{{0.25, 0.25, 0}, {0.5, 0.5, 0}}]]}]}]
