No worries. I just like continued lines typically. Everyone has their own style... with the lanyard hole I see what you are going for. Should look fine.
I usually will have one constant line on a knife, say the spine usually. Then I use a french curve and try to use continuing arcs that dissect themselves for the lower handle, recurve of the blade, etc. Some will say 'no straight lines with curves/vice versa,' But I tend to like a combination of the two, in as much as a knife can resemble a woman laying on the ground if the knife is sat on its spine.
As it sits, I really like the design you have chosen. Of knives I own, those are my favorite, though I've only made one of that style for a customer... It should prove to be a good user.
For a lanyard, location oartially depends on handle length as to whether it will interfere with a finger or heel of the palm. I use dead center a lot as I've found it cuts a little bit of the whip action should the knife be slung out vigorously. Not enough to really matter probably, so go with what feels and looks right to you.
By all means, use this place as a resource and a sounding board, it will shorten your learning curve. I know it has improved me greatly and really set the bar high. But, don't compromise your artistic integrity. If you are making a certain style of knife, obviously adhere to the basic foundation of that style, but if you are just cutting loose creatively then do what YOU want to do. I live a uniform and structured life in my day job. This is my chance to be unique, and honestly without it I'd go insane..
And just a tip I had to relearn the hard way trying to get some stuff done for Christmas. .. If you aren't in the mood to work on, or frustrated with a project, take a break for an hour or two or the rest of the day. Seems like mistakes abound in our frustration.
Cheers!
