The Hibees were bereft of ideas during an underwhelming Scottish Premiership clash in the capital, with a first-half header from James Collins which struck the post representing their only clear chance in the 0-0 stalemate.
After watching his side leave the field to a cacophony of jeers - much of which was aimed at himself as he disappeared down the tunnel - Fenlon conceded that his side were lacking imagination in front of their own fans.
Hibs are yet to win at Easter Road this term, and have scored one goal in four outings on their own patch, but the manager is hopeful his latest signings, from Kilmarnock and Istres, will remedy those problems.
Fenlon said: "I don't think there are too many positives we take from that. We had a lot of possession of the ball, but we have to be more precise and quicker in moving the ball, especially at home.
"We seem to be able to do it away from home but we have to be more precise when we get into good areas at Easter Road.
"Of course we are hopeful the new players will make a difference. Zoubir gives us something different to what we have and Paul is a different dimension to the type of strikers we have. They will be good additions to the squad."
Fenlon also believes the two new faces could prove vital to ending Collins' goalless streak, now spanning five games, since a £200,000 move from Swindon Town.
He added: "James got on the end of a great ball in and produced a great header and to be honest we haven't given him enough of that service. I think you can see what he can do if you get the service into him.
"As with every forward, you have to keep working hard to come out of these things. His record of scoring goals is very good and he needs to keep plugging away."
Meanwhile Ross County boss Derek Adams has hailed the battling spirit of his side after bouncing back from a shock 3-2 defeat against Stranraer in the Scottish Communities League Cup in midweek to claim a point in Leith.
The visitors arguably should have secured a second consecutive Premiership victory, with Mihael Kovacevic striking the post with a fine effort from distance.
Rocco Quinn and Graham Carey also passed up glorious opportunities, and Adams believes his side deserved to bounce back from their disappointing 520-mile round trip to the West coast with a win in Edinburgh.
The former Hibs assistant manager said: "We had a really long journey in midweek, but in our last two league matches we have kept two clean sheets and picked up four points.
"I think we should have won the match. We have had three gilt-edged opportunities.
"For a team like Ross County to come to Hibernian and come away with a point is very good and we should have won it. We were the better side over 90 minutes - nobody can argue against that."
