The stock/bond allocation is up to you, your risk tolerance, age, etc. I'm the same age and have nearly the same ratio, so of course I'll be fine with your choice :)
Second what TomTX said about the mid/small cap percentages. They are pretty small, you'll get more benefit (assuming of course that you are following some sort of rebalancing criteria - schedule or percentage, or whatever, as long as it's consistently applied) by increasing those to say at least the same as your international allocation. If you're not rebalancing, then never mind (but you might want to read one of William Bernstein's books on investing, he explains allocation and rebalancing better than most)
Finally, in addition to the dimension of risk (stock/bond), there is the dimension of country. How much to have in US vs International. 90% US / 10% International does not give the latter much contribution to your performance. I'm in a similar situation myself where my International is even lower than yours, and I'd like it to be higher. I'm aiming to raise it slowly over the next few years, maybe to at least 20%, probably should be even higher, up to 40%, but I'm not ready to go there yet. I'm fighting Home Bias as many of us are.
