Caught bluffing

[grouchie]

Ok, please give advice on this hand, every bit will help.

Also, if you were going to bluff on the flop like I did, how big of a bet would you have made it? just all in right away?
was my $25 too small?

and for the river, With most allof my money in there allready, Do I have to call the bet? Is folding even an option?
