looks good nigel,
i rest my hand against the bench when using the tweezers to place a part, helps with the shaking and alignment. use a 10x jewelers loup for mag/inspection. also 15mil glow core no clean eutectic solder works the best for me.
what are you using for small sig devices, sot-23 pkg I assume. no, it looks like you are using to-92 and thru-hole ecaps in a mixed tech layout.
have you discovered the fairchild fjv992/1845 devices? if you want to go away from to-92
