first impressions:

steeping your grains for an hour is unnecessary. all of the grains you buy anymore, with few exceptions, are very very modified. all your conversion has already occurred, at the temperatures you mentioned, within 30 minutes.

using liquid malt extract pretty much insures that your brew will be overly sweet and removes your ability to control the sweetness/caramel character. this is due to the process in making liquid malt extract. you are much better off using straight dry malt, if you are using malt extract, and trusting your use of the caramel malts.

while brown ales would probably be more common using an english style yeast, i see this is dutch. your use of german ale yeast is intriguing and will tend to make the beer cleaner than it otherwise would be. wyeast is a good product, for sure, and is what i use.

i'd drink this beer. i think it is going to be on the sweet side, but maybe that is what you are shooting for, as i have not had the privilege of drinking the target beer.
