My first shave with my brand new straight razor!

I purchased the "Classic Black" Dovo Straight Razor Set from Vintage Blades and received it the other day. It was so exciting. Unpacking it, laying each piece out...beautiful. (though the mug got cracked in transit, which is fine, it's just a mug).

Then the shave. I've been doing alot of reading on these forums, and was able to make an almost-uberlather with the col. conk almond soap. I've been using a wilkinson sword brush and soap which was put to shame by the wonders of a real badger hair brush and soap. A nice warm lather, and a sharp blade, the perfect start to a good shave.

A few WTG passes and the hair came off nicely. Now I don't have a full beard, (a curse/blessing at 28) but enough of a goatee to have to shave every other day. I got a fairly decent shave (about what i'd get with my mach 3), but afterwards it felt as though my face was on fire. I did go over some places numerous times as I'd miss bits, but always relathered to keep it slick.

Now I know my technique isn't the greatest; how can it be after just one shave, but am I doing something wrong? Or is this expected?
